I cannot access internet through R. My IT-guys told me that I should set the proxy and the port and then everything will be fine. Where can I set them? I use R 2.6.2 under Windows 2000 and these settings are those of the Internet Explorer (no password). I read http://cran.at.r-project.org/bin/windows/base/rw-FAQ.html#The-Internet-download-functions-fail_002e but staring R by "C:\Program

Could somebody please assist with the problem I have now. At our university certain changes have been made to users regarding accessing the internet. I have re-installed the (current) version of R, using custom settings (for Windows XP), choosing amongst other things "Internet2" somewhere. Now, when I wish to install new packages, I first have to select a CRAN mirror. R gives me a list

Hi, I am a new R user. I am using it develop regression models with categorical variables. Is there a way to force some regression coefficients to be zero for some of the values in a categorical variable (with 12 factor levels)? I am recoding the values to the default value (1st in the order of dummy's). But I am not sure if this is the correct approach if I want to force coefficients to be

I have some questions and observations about these: Will these replace manually setting options(CRAN), which doesn't work in R-2.1.0? In R-2.1.0, setRepositories() looks to see if options("repos") contains a CRAN entry and will not override that CRAN entry even if the $R_HOME/etc/repositories file (which setRepositories reads from) contains a CRAN entry. Why is this? The user

Hi I can't get R to connect to the internet. I am running R 1.7.1 on Windows XP and whenever I try to download packages etc from within R using the internet, it fails.

BUT i can't set up a shortcut for this as Windows (I hate Windows) complains

[Not sure if such wishlist item should go to R-help or R-devel...] It would be nice if an option can be added to the R for Windows installer that will add the --internet2 option to the command line in the shortcut that gets created. Also, is it possible to make that an option that can be set at the R prompt, or perhaps even better, as the default no matter how/where R is started? For those of

install/update.packages will have a lot of changes in 2.1.0, and I have been adding some widgets to go along with this. - Rather than just CRAN and BIOC, you have a character vector of repositories. There is a function setRepositories() to set the appropriate option(). - There is no default CRAN, but a function chooseCRANmirror() to set a mirror, which is invoked if you try to access

Just installed R on a new machine which is on a server. I am trying to download packages but seem to have trouble with our proxy settings. I have read the 2.19 section in R for Windows and tried what was suggested (setting http_proxy) but that did not help (still cannot connect). I think my problem is that we do not have a fixed port but use instead autoproxy. Has anyone encountered this problem

Hi all, Please, how could I calculate the time that two time segments has in common? Is there any function to perform this calculation? For instance, given four POSIXlt objects... endPeriod<-as.POSIXlt("2008-09-30") startPeriod<-as.POSIXlt("2007-10-01") endProject<-as.POSIXlt("2007-05-31") startProject<-as.POSIXlt("2006-12-01") that limit
